This is touching my test-of-training-strategies comments recently.

If we have a decent framework in place, then "obvious" spam would be
anything that is spam given complete data.

ie, assume we have 3000 ham and 3000 spam.  My training strategy would be to
perform a complete train over the entire database, and collect "correct"
scores for each item.  We then can test out various training strategies,
watching not only the fp/fn/unsure rates, but also deviance from the
"correct" score.

Do you believe we can reasonable formalize some tests for these strategies?

Yeah, 'cos when he is finished there are some nice training strategies I
would like him to work on <wink>
